Application filed April 4, 1905, Serial No. 258,743@ Renewed June 20, 1908'. Serial-No. 489,595.

erly, in the county of Essex and State of' Massachusetts, have invented certain new and useful Improvements in Sole-Roundi-ng Machines; and we do hereby declare the following to be a full, clear, and exact description' of the invention, such as will enable others skilled in the art to which it Yappertains-to make and use the same.

= The present invention relates to solechanneling operation. In machines of the rounding or sole channeling'machines of that class which comprise a pattern of the shape of the sole to be rounded or channeled, a knife carrier and -means for relatively moving the pattern and knife carrier to transfer the point of operation of the knlfe around the pattern.-

The object of the present proved means for actuating the knife'carrier during the relative movement of the knife carrier and pattern so as to cause the knife to readily follow the curves and angles of the pattern without any liability of injuring the pattern or of moving away from the edge of the pattern. at any point.

The invention is designed particularly for use in connection with patterns which present sharp curves or angles atcertain points, and particularly at the toe end of the pattern, although it isequallvcapable of be-- mg. usedadvantageously in connection with any form of pattern.

.A feature of the invention contemplates the provision of means for so actuating the carrier during the relative movement of the carrier and pattern that the carrier'is swung through a substantial arc while the knife is at the end of the pattern about a, center which remains substantially stationa'ry with relation to the pattern and in proximity to the end of the pattern during the'swfnging movement of the carrier. By so actuating the carrier the knife, after it reaches the end ofthe pattern, is caused to remain stationary in alinementwith the point about which the carrier is swinging, until thecarrier is swung around the end of thepattern, and

thus any liability of'theknife moving away from the pd-geof the pattern is avoided, and soles wlth narrow or sharp pointed toes ,can

be rounded or channeled 'in a satisfactory manner.

Another feature of the invention conte m plates imparting swinging movements' to the carrier, during the relative movement of the carrier and pattern, about a point fixed with relation to the carrieraand in maintaining said point in proximity to the edge of the pattern throughout the entire rounding or class-to which the present invention relates, the knife or knives are mounted to move inwardly and outwardly on the knife carrier, and are yieldingly pressed towards the pat- ,tern in order to maintain them' in the same -a position with relation to the edge of the patinventionis to provide a machine of this class having imtern throughout the rounding or'channeling operation.. By swinging 'the knife carrier about a point fixedwith relation to theca-rriefi and maintaining said point in proxim-.

from the specific description of the peeferred embodiment of the invention hereinafter contained.

It is to be understood that the broad features of the invention are not limited to any specific mechanism for actuating the knife carrier, and that the; devices andcombin'ations of parts hereinafter described and claimed are not limited to use in a 'machine having the specific construction illustrated in the drawings accompanying this application, and that, except as defined in the =will be obvious to those skilled invthe art 515 to, cut soles from strip-s M -Which is mounted t mov'en erticiflly in L-Qr 22 prqvidvd claims are not ill stru ctiim 0r arm.

. mdizllly, the yesul 51m su sx'ving- 1 H) ing and radial movements being to maintain the pivotal connection 21in proximity to the edge of the pattern and to cause the knife carrier to swing about this point as a center. In the construction illustrated, the. swinging and radial movements are imparted to the member22' by means of cams acting through intermediate mechanism.

The means for imparting radial movements to the member 22 comprise a stud 23 mounted upon the member 22 which engages a segmental slot 24 in a slide 25 which is an arm secured upon the upper'end of a rock shaft 31 journaled in the table. .To-the'. lower end of the rock shaft 31 is secured an; arm 32 provided with a stud engaging a cam groove in. a'stationary cam disk 34. a This cam disk is mounted upon the lower end ofthe standardll and is rigidly secured thereto. During the rotation ofth'e table 9 the stud on the arm 32 travels in the cam groove 33 and thus through the connections above described the desired radial movements are imparted to the member 22. i i p The means for imparting swinging movements to the member 22 comprises a block 37 engaging a slot 36 in the member 22' and pivotally mounted upon the outer end of an 'arm 38 projecting from a hub 39 mounted torotate freely upon the hub of the table 9. The hub 39 is provided with a segmental gear 40 which meshes with a segmental gear 41 upon a bent lever 42 pivotally mounted upon the table 9. Thelev-er 42 is providedwith, a stud which engages a cam groove 43 in the stationary cam disk 34 and thercam groove is sotshaped that during'the revolution of the table 9 the lever 42 is oscillated,

' and through the hub 3%), arm 38 and block travels along the segmental slot'24 in the 31 the desired swinging movements are impartedto the member 22. During the swinging movements of the member 22 the stud 23 slide 25, and during the radial movements of themember 22 t he-block"37 travels along J'by reason of the engagement of the knifethe slot 36 in the member 22, so that neither the swinging nor the radial movcments'are nterfered with. he swinging movements" ;y'hioh are imparted to the member.. 22 during the rotation of thetahle 9 move the pivotal connection 21 with. relation to the table, and

carrier' by the. pivot 20 causethe knife carrier to swing about the point 21 as a center,

' The swinging movements about the point 21.

whichare'tl'tusvimparted to the knife carrier tend to maintain the knife carrier in-snoh "from the hub 39.-

positions with relation to the pattern that the knife holder can move readily inwardly and outwardly on the carrier so as to follow the curves and angles of the pattern.

The cam groove 43 and the mechanism ac tu'atedthereby for swinging the member 22 may be relied upon to impart the desired swinging movements to the carrier 15 about the point 21L In order to increase the extent ofthe swinging movements lmpa'rted to the knife carrier, and at the same time obvlate the necessity of sharp changes-in the curves s lated whenever the hub 39 is rotated with re flation to the hub of thewtable, the rotation of the hub 39 causing a simulta'neousimovement' of the pivotal connection 21 and the pivot- 20 with relation to the table in opposite -directions. v p t y In themachine illustrated in the drawings,'the shape and arrangement of the cam grooves 33, 43 and 45 and the mechanism between the cam grooves and the knife car rier are suc'hthat the point 21'on the carrier is caused to move in a path closely approximatingin shape that of the pattern, andthe knife carrier s swung about the point 21 so that the direction of the inward and outward movements of the knife holder on the knife carrier is. maintained substantially normalto the curves of the pattern throughout the entire rounding and channeling operation. Also, the point 21 is caused to re main stationary when itreaches the end of the pattern until the knife carrier has been swung about the point 21 as a'center from one side of the pattern to the other. There is .thus no tendency for the knives to move away from the pattern in passing around the ,toe of a narrow or pointed pattern. By maintaining the direction of the inward and outward movements of the knife holder on theknife carrier substantially normal to the curves of the pattern While passing along the sides as well-as'around thee'nds of the pattermthe knives are also caused to pass around the sharp curve or angles at the junction of. the shank and foa'epart without' drawings, the slot 35 is curved, being struck about the pivotal connection of the link 37 lathe construction illustrated in the n n ti e 3,1".
